I am having concerns about my Artist projects on my new computer.

Thank you . I don’t know enough about my problem to ask a sensible question , I suppose. I have downloaded the Cubase Artist 9 to my new computer and my access dongle allows me to use Cubase. My compositions , supposedly moved to new computer , are nowhere to be found on either computer . I was hoping when I brought up Cubase, it would look the same as two weeks ago on the old computer with the same projects . I don’t know how to find them. Months of work floating around somewhere. Anyway, thanks again.
